HIV/AIDS status disclosure increases support, behavioural change and, HIV prevention in the long term: a case for an Urban Clinic, Kampala, Uganda

BackgroundDisclosure of HIV status supports risk reduction and facilitates access to prevention and care services, but can be inhibited by the fear of negative repercussions. We explored the short and long-term outcomes of disclosure among clients attending an urban HIV clinic in Uganda.MethodsQualitative semi-structured interviews were administered to a purposeful sample of 40 adult HIV clients that was stratified by gender. The information elicited included their lived experiences and outcomes of disclosure in the short and long term. A text data management software (ATLAS.ti) was used for data analysis. Codes were exported to MS Excel and pivot tables, and code counts made to generate statistical data.ResultsOf the 134 short-term responses elicited during the interview regarding disclosure events, most responses were supportive including encouragement, advice and support regarding HIV care and treatment. The results show on-disclosing to spouse, there was more trust, and use of condoms for HIV prevention. Only one third were negative responses, like emotional shock and feeling of distress. The negative reactions to the spouses included rejection, shock and distress in the short term. Even then, none of these events led to drastic change such as divorce. Other responses reflected HIV prevention and call for behavioural change and advice to change sexual behaviour, recipient seeking HIV testing or care. Women reported more responses of encouragement compared to men. Men reported more preventive behaviour compared to women. Of the 137 long-term outcomes elicited during disclosure, three quarters were positive followed by behavioral change and prevention, and then negative responses. Men reported increased care and support when they disclosed to fellow men compared to when women disclosed to women. There was better or not change in relationship when women disclosed to women than when women disclosed to men.ConclusionsThere is overwhelming support to individuals that disclose their HIV status, especially in the long term. Besides, gender appears to influence responses to HIV disclosure, highlighting the need for gender specific disclosure support strategies.

Hypertension and associated risk factors in individuals infected with HIV on antiretroviral therapy at an urban HIV clinic in Uganda

Abstract Background Scale-up of antiretroviral therapy (ART) might precipitate an increase in non-communicable diseases (NCDs) in adults infected with HIV in sub-Saharan Africa based on data from resource-rich settings. Hypertension is a major modifiable risk factor for cerebrovascular and cardiovascular NCDs. We estimated prevalence, incidence, and risk factors for incident hypertension in adults infected with HIV on ART at an urban clinic in Uganda. Methods From a cohort of adults infected with HIV (>18 years) who initiated ART between Jan 1, 2005, and Jan 3, 2012, at the Infectious Diseases Institute clinic in Kampala, we report the prevalence, incidence, and cumulative incidence (with death as a competing risk) of hypertension (≥140/90 mm Hg). Risk factors for hypertension were evaluated with Cox proportional hazards regression. Findings Of 9806 individuals who initiated ART, 6351 (64·8%) were women, median age was 36 years (IQR 31–42), and median follow-up was 3·9 years (2·2–5·9). Overall prevalence of hypertension was 15·1% (1472 individuals); older individuals (>50 years) had higher prevalence (299, 38·6%). By year 1, cumulative incidence was 1% and by year 5, it was 3·6%. Overall incidence was 19 cases per 1000 person-years. Multivariate regression showed male sex, older age, increasing body-mass index, and use of stavudine at initiation was associated with an increased rate of hypertension. Interpretation Of our patients, we noted a prevalence of hypertension between 14·6% and 28·5%, similar to the general Ugandan population. Besides traditional risk factors for hypertension, use of stavudine was also identified. Awareness of NCD comorbidity and AIDS-associated risk factors are increasingly important for clinicians caring for adults on ART in sub-Saharan Africa.

Subclinical Atherosclerosis among HIV-Infected Adults Attending HIV/AIDS Care at Two Large Ambulatory HIV Clinics in Uganda

BackgroundThe increased immune activation and inflammation of chronic HIV-infection and the characteristic dyslipidemias associated with HIV infection and antiretroviral therapy (ART) contribute to an increased risk of atherosclerotic vascular disease among HIV-infected adults. There is an emerging need to understand determinants of cardiovascular disease (CVD) among individuals aging with HIV in sub-Saharan Africa. We determined the prevalence of subclinical atherosclerosis [carotid intima media thickness (CIMT) ≥0.78 mm] and its correlation with traditional CVD risk factors among HIV-infected adults.MethodsIn a cross-sectional study, HIV-infected adults (ART-naïve and ART-treated) were consecutively selected from patients' enrollment registers at two large HIV clinics at Mulago Hospital, Kampala, Uganda. We measured traditional CVD risk factors including age, biophysical profile, fasting blood sugar and serum lipid profile as well as biomarkers of inflammation. High resolution ultrasound was used to measure common carotid CIMT.ResultsOf 245 patients, Median age [Interquartile range (IQR)] 37 years (31–43), 168 (69%) were females; and 100 (41%) were ART-treated for at least 7 years. Overall, 34/186 (18%) had subclinical atherosclerosis; of whom 15/108 (14%) were ART-naïve whereas 19/78 (24%) were ART-treated. Independent predictors of subclinical atherosclerosis included age [odds ratio (OR) 1.83 per 5-year increase in age; 95% confidence interval (CI) 1.24–2.69; p = 0.002], body mass index (BMI); OR 1.15; CI 1.01–1.31; p = 0.041 and high low density lipoprotein (LDL) [OR 2.99; CI 1.02–8.78, p = 0.046]. High sensitivity C-reactive protein (hsCRP) was positively correlated with traditional cardio-metabolic risk factors including waist circumference (r = 0.127, p = 0.05), triglycerides (r = 0.19, p = 0.003) and Total Cholesterol: High Density Lipoprotein ratio (TC:LDL) (r = 0.225, p<0.001).ConclusionThe prevalence of subclinical atherosclerosis was 18% among HIV-infected adults in Uganda. Traditional CVD risk factors were associated with subclinical atherosclerosis. We recommend routine assessment of traditional CVD risk factors within HIV care and treatment programs in sub-Saharan Africa.

Operational Implementation of LED Fluorescence Microscopy in Screening Tuberculosis Suspects in an Urban HIV Clinic in Uganda

BackgroundLight emitting diode (LED) fluorescence microscopy (FM) is an affordable, technology targeted for use in resource-limited settings and recommended for widespread roll-out by the World Health Organization (WHO). We sought to compare the operational performance of three LED FM methods compared to light microscopy in a cohort of HIV-positive tuberculosis (TB) suspects at an urban clinic in a high TB burden country.MethodsTwo spot specimens collected from TB suspects were included in the study. Smears were stained using auramine O method and read after blinding by three LED-based FM methods by trained laboratory technicians in the Infectious Diseases Institutelaboratory. Leftover portions of the refrigerated sputum specimens were transported to the FIND Tuberculosis Research Laboratory for Ziehl Neelsen (ZN) smear preparation and reading by experienced technologist as well as liquid and solid culture.Results174 of 627 (27.8%) specimens collected yielded one or more positive mycobacterial cultures. 94.3% (164/174) were M. tuberculosis complex. LED FM was between 7.3–11.0% more sensitive compared to ZN microscopy. Of the 592 specimens examined by all microscopy methods, there was no significant difference in sensitivity between the three LED FM methods. The specificity of the LED FM methods was between 6.1% and 7.7% lower than ZN microscopy (P<0.001), although exclusion of the single poor reader resulted in over 98% specificity for all FM methods.ConclusionsLaboratory technicians in routine settings can be trained to use FM which is more sensitive than ZN microscopy. Despite rigorous proficiency testing, there were operator-dependent accuracy issues which highlight the critical need for intensive quality assurance procedures during LED FM implementation. The low sensitivity of FM for HIV-positive individuals particularly those with low CD4 T cell counts, will limit the number of additional patients found by LED FM in countries with high rates of HIV co-infection.

A Pharmacy-Only Refill Program at a Large HIV Clinic in Uganda

The purpose of this study was to assess patients' experience and satisfaction with pharmacy-only refill program (PRP) and to compare those who were removed from the PRP with those still in the program. A sample of 446 patients was selected from 1503 patients on antiretroviral therapy that had been enrolled in the PRP for at least 24 months. The study used interviewer-administered questionnaires to assess patients' experience and satisfaction with PRP. Of the 446 patients, 133 (29.8%) were removed from the PRP. By multivariate analysis, it was found that wanting to see a clinician before their scheduled clinic visit, Christian religion, and not understanding why they were enrolled in PRP were associated with having been removed from the PRP. Patients felt that the greatest benefit from the program was the time that they saved to do other activities. Patients preferred to collect their medication every 3 months instead of every month. All patients interviewed scored the program high, and all recommended that the PRP should continue. Stable patients prefer to see clinicians less frequently and visit clinic less often.

Risk of Tuberculosis after Antiretroviral Treatment Initiation: A Comparison between Efavirenz and Nevirapine Using Inverse Probability Weighting

There is a high incidence of tuberculosis (TB) early after antiretroviral therapy (ART) initiation. This historical cohort study evaluated the association of efavirenz (EFV) compared to nevirapine (NVP) with post-ART TB among patients initiated on first-line ART from 2005 to 2009 in a large, urban HIV clinic in Uganda. Hazard ratios (HR) for developing TB were computed using multivariable Cox proportional hazards models with inverse weighting of the probability of being prescribed NVP or EFV (calculated by a multivariable logistic regression model), stratifying by baseline CD4+ T-cell count. Adjustment for time-updated CD4+ T-cell count, restriction of the analysis to patients remaining in follow-up and a TB-free survival analysis were performed as sensitivity analyses. ART was initiated in 5,797 patients; 66% were women with a mean age of 37 years (SD 9) and a median baseline CD4+ T-cell count of 117 cells/mm3 (IQR 43-182). Overall, 60% (n = 3,484) were initiated on NVP and 40% (n = 2,313) on EFV. In the first 2 years of ART, 377 patients developed TB. The use of EFV compared to NVP was independently associated with higher TB incidence in patients with a baseline CD4+ T-cell count < 100 cells/mm3 (HR 2.05 [95% CI 1.29, 3.27]; P = 0.003), but not at higher CD4+ T-cell counts (HR 0.71 [95% CI 0.39, 1.31]; P = 0.428). These estimates were robust to all sensitivity analyses. There was a higher incidence of TB in patients with baseline CD4+ T-cell counts < 100 cells/mm3 initiated on EFV compared to those initiated on NVP. Further research in a trial setting or a larger multisite observational cohort is needed to confirm these findings.

Fertility and contraceptive decision-making and support for HIV infected individuals: client and provider experiences and perceptions at two HIV clinics in Uganda

BackgroundSome people living with HIV/AIDS (PLHIV) want to have children while others want to prevent pregnancies; this calls for comprehensive services to address both needs. This study explored decisions to have or not to have children and contraceptive preferences among PLHIV at two clinics in Uganda.MethodsThis was a qualitative cross-sectional study. We conducted seventeen focus group discussions and 14 in-depth interviews with sexually active adult men and women and adolescent girls and boys, and eight key informant interviews with providers. Overall, 106 individuals participated in the interviews; including 84 clients through focus group discussions. Qualitative latent content analysis technique was used, guided by key study questions and objectives. A coding system was developed before the transcripts were examined. Codes were grouped into categories and then themes and subthemes further identified.ResultsIn terms of contraceptive preferences, clients had a wide range of preferences; whereas some did not like condoms, pills and injectables, others preferred these methods. Fears of complications were raised mainly about pills and injectables while cost of the methods was a major issue for the injectables, implants and intrauterine devices. Other than HIV sero-discordance and ill health (which was cited as transient), the decision to have children or not was largely influenced by socio-cultural factors. All adult men, women and adolescents noted the need to have children, preferably more than one. The major reasons for wanting more children for those who already had some were; the sex of the children (wanting to have both girls and boys and especially boys), desire for large families, pressure from family, and getting new partners. Providers were supportive of the decision to have children, especially for those who did not have any child at all, but some clients cited negative experiences with providers and information gaps for those who wanted to have children.ConclusionsThese findings show the need to expand family planning services for PLHIV to provide more contraceptive options and information as well as expand support for those who want to have children.

Unrecognised tuberculosis at antiretroviral therapy initiation is associated with lower CD4+ T cell recovery

To investigate whether an unrecognised diagnosis of tuberculosis (TB) at the start of antiretroviral therapy (ART) influences subsequent CD4+ T cell (CD4) count recovery in an urban HIV clinic in Uganda. In a retrospective cohort study, a multivariable polynomial mixed effects model was used to estimate CD4 recovery in the first 96 weeks of ART in two groups of patients: prevalent TB (started ART while on TB treatment), unrecognised TB (developed TB within 6 months after start ART). Included were 511 patients with a median baseline CD4 count of 57 cells/mm(3) (interquartile range: 22-130), of whom 368 (72%) had prevalent TB and 143 (28%) had unrecognised TB. Compared with prevalent TB, unrecognised TB was associated with lower CD4 count recovery at 96 weeks: -22.3 cells/mm(3) (95% confidence interval -43.2 to -1.5, P = 0.036). These estimates were adjusted for gender, age, baseline CD4 count and the use of zidovudine-based regimen. Unrecognised TB at the time of ART initiation resulted in impaired CD4 recovery compared with TB treated before ART initiation. More vigilant screening with more sensitive and rapid TB diagnostics prior to ART initiation is needed to decrease the risk of ART-associated TB and sub-optimal immune reconstitution.

Implementation and effect of intensified case finding on diagnosis of tuberculosis in a large urban HIV clinic in Uganda: a retrospective cohort study.

BackgroundIncreased detection of tuberculosis (TB) using intensified or active case finding (ICF) is one of the cornerstones of the Stop TB Strategy, and contrasts with passive case finding (PCF) which relies on self-reported symptoms. There is no clear guidance on implementation strategies. We implemented ICF in addition to ongoing PCF in our large urban HIV clinic in July 2010 using a twice-daily announcement screen method by a trained peer educator, asking waiting patients to self-refer to a trained peer supporter for screening of TB symptoms. We sought to determine the associated effect on TB case detection.MethodsSuspects were investigated by sputum smear, chest X-ray and ultrasound, if indicated. Routinely collected clinical and laboratory data were merged with the ICF register and TB clinic data for patients attending the clinic in 2010. We compared the yield of TB cases (defined as the prevalence of newly diagnosed TB cases in the screened population), the type of TB diagnosed and the total cost per TB case identified (in United States Dollars [USD]) for the period before and after ICF implementation.ResultsOf the 20,456 patients who visited the clinic in 2010, 614 were identified as TB suspects, 220 pre-ICF and 394 post-ICF (229 via PCF and 165 via ICF). The proportion diagnosed with TB dropped from 66% to 48% (60% in suspects identified through PCF and 31% through ICF). During the post-ICF period, TB suspects identified through ICF compared to PCF identification were more likely to be female, older, on ART and to have been enrolled in HIV care for a longer duration. The yield of combined PCF and ICF screening was 1.4% pre-ICF and 1.7% post-ICF with a cost per TB case identified of 12.29 USD and 21.80 USD, respectively.ConclusionsImplementation of ICF in a large HIV clinic yielded more TB suspects and cases, but substantially increased costs and was unable to capture the majority of TB suspects who were referred for diagnosis by clinicians through PCF. The overall yield of TB cases in a mature HIV clinic was low, although targeted screening of those recently enrolled in care may increase the yield.

Integration of HIV and TB services results in improved TB treatment outcomes and earlier prioritized ART initiation in a large urban HIV clinic in Uganda.

The World Health Organization recommends that treatment of tuberculosis (TB) in HIV-infected patients should be integrated with HIV care. In December 2008, a separate outdoor-integrated TB/HIV clinic was instituted for attendees of a large urban HIV clinic in Uganda. We sought to evaluate associated TB and HIV treatment outcomes. Routinely collected clinical, pharmacy, and laboratory data were merged with TB clinic data for patients initiating TB treatment in 2009 and with TB register data for patients in 2007. TB treatment outcomes and (timing of) antiretroviral therapy (ART) initiation in ART-naive patients [overall and stratified by CD4+ T cell (CD4) count] in 2007 and 2009 were compared. Nosocomial transmission rates could not be assessed. Three hundred forty-six patients were initiated on TB treatment in 2007 and 366 in 2009. Median CD4 counts at TB diagnosis did not differ. TB treatment cure or completion increased from 62% to 68%, death or default decreased from 33% to 25% (P < 0.001). Fewer ART-naive TB patients were initiated on ART in 2009 versus 2007 (57% and 66%, P = 0.031), but this decrease was only in patients with CD4 counts >250 cells per cubic millimeter (19% vs. 48%, P = 0.003). More patients were started on ART during TB treatment (94% vs. 78%, P < 0.001). Moreover, the majority were now initiated during intensive phase (60% vs. 23%, P < 0.001). Integration of TB and HIV care has led to improved TB treatment outcomes and earlier, prioritized ART initiation. This supports rollout of a fully integrated TB/HIV service delivery model throughout high-prevalence TB and HIV settings.

Earlier initiation of antiretroviral therapy, increased tuberculosis case finding and reduced mortality in a setting of improved HIV care: a retrospective cohort study

High early mortality after antiretroviral therapy (ART) initiation in resource-limited settings is associated with low baseline CD4 cell counts and a high burden of opportunistic infections. Our large urban HIV clinic in Uganda has made concerted efforts to initiate ART at higher CD4 cell counts and to improve diagnosis and care of patients coinfected with tuberculosis (TB). We sought to determine associated treatment outcomes. Routinely collected data for all patients who initiated ART from 2005 to 2009 were analysed. Median baseline CD4 cell counts by year of ART initiation were compared using the Cuzick test for trend. Mortality and TB incidence rates in the first year of ART were computed. Hazard ratios (HRs) were calculated using multivariable Cox proportional hazards models. First-line ART was initiated in 7659 patients; 64% were women, and the mean age was 37 years (standard deviation 9 years). Median baseline CD4 counts increased from 2005 to 2009 [82 cells/μL (interquartile range (IQR) 24, 153) to 148 cells/μL (IQR 61, 197), respectively; P<0.001]. The mortality rate fell from 6.5/100 person-years at risk (PYAR) [95% confidence interval (CI) 5.5-7.6 PYAR] to 3.6/100 PYAR (95% CI 2.2-5.8 PYAR). TB incidence rates increased from 8.2/100 PYAR (95% CI 7.1-9.5 PYAR) to 15.6/100 PYAR (95% CI 12.4-19.7 PYAR). A later year of ART initiation was independently associated with decreased mortality (HR 0.91; 95% CI 0.83-1.00; P=0.04). Baseline CD4 cell counts have increased over time and are associated with decreased mortality. Additional reductions in mortality might be a result of a better standard of care and increased TB case finding. Further efforts to initiate ART earlier should be prioritized even in a setting of capped or reduced funding for ART programmes.

Research Capacity–Building Program for Clinicians and Staff at a Community-Based HIV Clinic in Uganda: A Pre/Post Evaluation

Developing capacity for HIV research and clinical practice is critically needed in resource-limited countries. The purpose of this study was to evaluate a research capacity-building program for community-based participants in the preparation and conduct of mobile phone-based technology interventions. A descriptive, cross-sectional design was used. Participants completed self-report surveys at three time points. Thirty-three participated in the situational analysis, and all (100%) felt that the research training was needed. For the interim evaluation, more than 96.8% (n = 30) reported increased knowledge and confidence and attributed this to the training. Fourteen participants completed the final evaluation. Dedicated time away from work was an important factor to facilitate recruitment and data collection, followed by financial incentives to commute to data collection sites. Expertise through supervision and mentorship for participants and sustained funding for research projects are critical to the innovation needed to improve HIV prevention and care outcomes.

Factors Associated with Intention to Conceive and its Communication to Providers Among HIV Clients in Uganda

Persons living with HIV/AIDS (PLHA) must discuss their fertility intentions with healthcare providers to receive the support needed to have children safely and limit transmission risks. However, few quantitative studies have examined correlates of fertility intentions, let alone the communication of such intentions with providers. We examined the prevalence and correlates of intentions to have children, and comfort discussing such plans with one's providers, in HIV clients at two HIV clinics in Uganda. Cross-sectional self-report data were collected from 233 patients who had primary partners. Bivariate correlates significant at the P < 0.10 level were included in logistic regression analysis. Of the 233 participants, 103 (44%) reported an intention to conceive a child in the near future. In multivariate analysis, younger age of both the patient and their partner, better physical health functioning and higher internalized HIV stigma were associated with having fertility intentions. One-third (35%) of those with fertility intentions expressed having difficulty discussing these intentions with their providers, which was associated with receiving care at the rural clinic and greater internalized HIV stigma. These findings highlight the need for reproductive health services that help clients accept themselves as PLHA and their fertility rights, thus promoting patient-doctor communication needed to promote safe child conception and delivery outcomes.

Uptake of family planning methods and unplanned pregnancies among HIV‐infected individuals: a cross‐sectional survey among clients at HIV clinics in Uganda

BackgroundPrevention of unplanned pregnancies among HIV-infected individuals is critical to the prevention of mother to child HIV transmission (PMTCT), but its potential has not been fully utilized by PMTCT programmes. The uptake of family planning methods among women in Uganda is low, with current use of family planning methods estimated at 24%, but available data has not been disaggregated by HIV status. The aim of this study was to assess the utilization of family planning and unintended pregnancies among HIV-infected people in Uganda.MethodsWe conducted exit interviews with 1100 HIV-infected individuals, including 441 men and 659 women, from 12 HIV clinics in three districts in Uganda to assess the uptake of family planning services, and unplanned pregnancies, among HIV-infected people. We conducted multivariate analysis for predictors of current use of family planning among women who were married or in consensual union and were not pregnant at the time of the interview.ResultsOne-third (33%, 216) of the women reported being pregnant since their HIV diagnoses and 28% (123) of the men reported their partner being pregnant since their HIV diagnoses. Of these, 43% (105) said these pregnancies were not planned: 53% (80) among women compared with 26% (25) among men. Most respondents (58%; 640) reported that they were currently using family planning methods. Among women who were married or in consensual union and not pregnant, 80% (242) were currently using any family planning method and 68% were currently using modern family planning methods (excluding withdrawal, lactational amenorrhoea and rhythm). At multivariate analysis, women who did not discuss the number of children they wanted with their partners and those who did not disclose their HIV status to sexual partners were less likely to use modern family planning methods (adjusted OR 0.40, range 0.20-0.81, and 0.30, range 0.10-0.85, respectively).ConclusionsThe uptake of family planning among HIV-infected individuals is fairly high. However, there are a large number of unplanned pregnancies. These findings highlight the need for strengthening of family planning services for HIV-infected people.

Zinc status in HIV infected Ugandan children aged 1-5 years: a cross sectional baseline survey

BackgroundLow concentrations of serum zinc have been reported in HIV infected adults and are associated with disease progression and an increased risk of death. Few studies have been conducted in HIV infected children in Africa. We determined serum zinc levels and factors associated with zinc deficiency in HIV infected Ugandan children.MethodsWe measured the baseline zinc status of 247 children aged 1-5 years enrolled in a randomised trial for multiple micronutrient supplementation at paediatric HIV clinics in Uganda (http://ClinicalTrials.gov NCT00122941). Zinc status was determined using inductively coupled atomic emission spectrophotometry (ICP-AES). Clinical and laboratory characteristics were compared among zinc deficient (zinc < 10.0 μmol/L) and non deficient children. Logistic regression was used to determine predictors of low serum zinc.ResultsOf the 247 children, 134 (54.3%) had low serum zinc (< 10.0 μmol/L). Of the 44 children on highly active antiretroviral therapy (HAART), 13 (29.5%) had low zinc compared to 121/203 (59.6%) who were not on HAART. Overall, independent predictors of low zinc were fever (OR 2.2; 95%CI 1.1 - 4.6) and not taking HAART (OR 3.7; 95%CI 1.8 - 7.6).ConclusionAlmost two thirds of HAART naïve and a third of HAART treated HIV infected children were zinc deficient. Increased access to HAART among HIV infected children living in Uganda might reduce the prevalence of zinc deficiency.

Evaluation of the Efficiency of Patient Flow at Three HIV Clinics in Uganda

With dramatic increases in antiretroviral therapy (ART) provision, many clinics in sub-Saharan Africa are congested, but little attention has focused on the efficiency of clinics. Between April and June 2008, we conducted a time-and-motion study to assess patient flow at three HIV clinics in Uganda. Mulago HIV Clinic had 6,700 active patients, compared with 2,700 at Mbarara Municipal Council Clinic (MMC) and 2,800 at Reachout Mbuya (ROM). Mulago had six doctors and eight nurses; MMC had two doctors and two nurses, and ROM had two doctors and 12 nurses. Mulago and MMC used a doctor-led model, whereas ROM used a nurse-led model. Randomly selected patients were tracked, with data collected on time waiting and time spent with providers. Patients were categorized as new, preparing for ART, early ART, stable ART, or non-ART. Doctors indicated whether the patients they saw warranted their consultation. Data were collected on 689 patients (230 at Mulago, 229 at MMC, and 230 at ROM). Overall waiting time was longest at ROM (274 min; 209-346) and Mulago ISS (270 min; 230-336) compared with MMC (183 min; 148-233). Nurse-clinicians at ROM spent twice the time with patients compared with the doctors at Mulago. At Mulago, doctors indicated that 27% of the patients they reviewed did not need to see a doctor, compared with 45% at MMC. Task-shifting may not be efficient in terms of time. More-effective triage and longer visit intervals could improve patient flow and capacity for cost-effective scale-up.

Baseline severe anaemia should not preclude use of zidovudine in antiretroviral‐eligible patients in resource‐limited settings

BackgroundStavudine is no longer recommended as part of first-line therapy for patients initiating antiretroviral therapy (ART) in Uganda. Most patients are currently initiated on zidovudine-containing regimens, which can induce anaemia. We investigated the risk factors for early severe anaemia in the first six months of ART initiation.MethodsWe defined baseline (ART initiation) anaemia as haemoglobin (Hb) ≤9.5 g/dL, baseline severe anaemia as Hb ≤8 g/dL, and early severe anaemia as Hb ≤8 g/dL within six months of ART initiation. Risk factors for the development of early severe anaemia were analyzed using a multivariable logistic regression model.ResultsIn total, 5494 patients initiated ART, 821 (15%) had baseline anaemia, and 296 (5%) had baseline severe anaemia. Early severe anaemia occurred in 109 (4%) of 3105 patients who had at least one Hb measurement in the first six months on ART. Patients with baseline anaemia had a larger increase in Hb (median g/dL [IQR]) within the first six months compared with non-anaemic patients (2.9 [1.7, 4.6] vs. 0.7 [-0.2, 1.7], p < 0.0001). Having a new tuberculosis episode OR 3.69 (95% CI 1.64 - 8.32), MCV <80fL OR 1.60 (95% CI 1.01- 2.52) and baseline severe anaemia OR 5.27 (95% CI 3.00 - 9.26) were associated with early severe anaemia. Initiation on a zidovudine-based regimen was not associated with an increased risk of early severe anaemia.ConclusionsAmong patients in an urban HIV clinic in Uganda, severe anaemia is modestly prevalent at ART initiation and improves with ART in the majority of patients. These data suggest that baseline severe anaemia should not be used as a criterion for avoiding the use of zidovudine in patients initiating ART in resource-limited settings.

Effect of multiple micronutrient supplementation on survival of HIV‐infected children in Uganda: a randomized, controlled trial

BackgroundMicronutrient deficiencies compromise the survival of HIV-infected children in low-income countries. We assessed the effect of multiple micronutrient supplementation on the mortality of HIV-infected children in Uganda.MethodsIn a randomized, controlled trial, 847 children aged one to five years and attending HIV clinics in Uganda were stratified by antiretroviral therapy (ART, n = 85 versus no ART, n = 762). The children were randomized to six months of either: twice the recommended dietary allowance of 14 micronutrients as the intervention arm (vitamins A, B1, B2, niacin, B6, B12, C, D and E, folate, zinc, copper, iodine and selenium); or the standard recommended dietary allowance of six multivitamins (vitamins A, D2, B1, B2, C and niacin) as a comparative "standard-of-care" arm. Mortality was analyzed at 12 months of follow up using Kaplan Meier curves and the log rank test.ResultsMortality at 12 months was 25 out of 426 (5.9%) children in the intervention arm and 28 out of 421 (6.7%) in the comparative arms: risk ratio 0.9 (95% CI 0.5 - 1.5). Two out of 85 (2.4%) children in the ART stratum died compared with 51 out of 762 (6.7%) in the non-ART stratum. Of those who died in the non-ART stratum, 25 of 383 (6.5%) were in the intervention arm and 26 of 379 (6.9%) in the comparative arm; risk ratio 1.0 (95% CI 0.6 - 1.6). There was no significant difference in survival at 12 months (p = 0.64, log rank test). In addition, there was no significant difference in mean weight-for-height at 12 months; 0.70 ± 1.43 (95% CI 0.52 - 0.88) for the intervention versus 0.59 ± 1.15 (95% CI 0.45 - 0.75) in the comparative arm. The mean CD4 cell count; 1024 ± 592 (95% CI 942 - 1107) versus 1060 ± 553 (95% CI 985 - 1136) was also similar between the two groups.ConclusionsTwice the recommended dietary allowance of 14 micronutrients compared with a standard recommended dietary allowance of six multivitamins for six months was well tolerated, but it did not significantly alter mortality, growth or CD4 counts. Future intervention studies should carefully consider: (1) the composition and dosing of the supplements; and (2) the power needed to detect a difference between arms.Trial RegistrationClinicalTrials.gov Identifier: NCT00122941

The WHOMEN’s Scale (Women’s HAART Optimism Monitoring and EvaluatioN Scale v.1) and the Association with Fertility Intentions and Sexual Behaviours Among HIV-Positive Women in Uganda

The objective of this study was to develop a reliable HAART optimism scale among HIV-positive women in Uganda and to test the scale's validity against measures of fertility intentions, sexual activity, and unprotected sexual intercourse. We used cross-sectional survey data of 540 women (18-50 years) attending Mbarara University's HIV clinic in Uganda. Women were asked how much they agreed or disagreed with 23 statements about HAART. Data were subjected to a principal components and factor analyses. Subsequently, we tested the association between the scale and fertility intentions and sexual behaviour using Wilcoxon rank sum test. Factor analysis yielded three factors, one of which was an eight-item HAART optimism scale with moderately high internal consistency (alpha = 0.70). Women who reported that they intended to have (more) children had significantly higher HAART optimism scores (median = 13.5 [IQR: 12-16]) than women who did not intend to have (more) children (median = 10.5 [IQR: 8-12]; P < 0.0001). Similarly, women who were sexually active and who reported practicing unprotected sexual intercourse had significantly higher HAART optimism scores than women who were sexually abstinent or who practiced protected sexual intercourse. Our reliable and valid scale, termed the Women's HAART Optimism Monitoring and EvaluatioN scale (WHOMEN's scale), may be valuable to broader studies investigating the role of HAART optimism on reproductive intentions and sexual behaviours of HIV-positive women in high HIV prevalence settings.
